Software Developer Rust (all genders)
We're transforming PRTG Network Monitor from its Delphi roots into a modern, modular architecture using AI-assisted workflows. We're refactoring and re-architecting to build clean, scalable, properly isolated modules — starting with production modules in 2026.
You will be an engineer in the Rust stream, owning modules from design through delivery. Working from architectural specifications, you'll translate domain knowledge into production-quality Rust code that integrates with our legacy Delphi core during the transition period.
AI is central to how we work. You'll use AI tools like Claude Code daily — for code generation, review, refactoring, and problem-solving. This isn't about outsourcing thinking to AI; it's about amplifying your capabilities. You'll need to guide AI effectively, validate its output critically, and help evolve how we use these tools as a team.
YOUR TASKS
Implement Rust modules from implementation-ready specificationsDesign within architectural constraints — detailed design, implementation planning, and task breakdown for your modulesWrite tests — unit and integration tests to catch bugs earlyShape our AI-assisted workflow — we use Claude Code and other AI tools as integral parts of our development process; you'll help evolve how we leverage AI for code generation, review, and quality assuranceEnsure AI-generated code meets our quality standards — review, refine, and hold AI output to the same bar as human-written codeCollaborate with architects to refine implementation details and surface edge cases from the legacy systemDocument your work — maintain clear documentation for modules you implementOwn complex modules end-to-end — take full responsibility for significant features from design to deliveryMentor engineers — conduct code reviews, pair on difficult problems, and help teammates growDrive technical decisions within your modules — evaluate approaches and ensure qualityContribute to architectural decisions on module boundaries, interface contracts, and data flowsHelp establish patterns that will scale as we grow to multiple teamsYOUR PROFILE
MUST HAVE
5-7 years software development experience with hands-on Rust — you understand ownership, lifetimes, and the borrow checker intuitively; you've built production systemsTrack record of technical ownership — you've owned significant features or systems end-to-end and delivered them successfullyTeam player who elevates others — you jump in where needed, help teammates unblock, and actively share knowledgeExperience with systems programming, performance-critical code, or backend servicesProven experience with AI-assisted development — you've integrated tools like Claude, Copilot, or similar into your daily workflow and have opinions on what works. You want to push the boundaries of what's possible and help us define best practices for AI-augmented software engineering at scale.Skilled in getting the most out of AI — you understand context engineering, write effective prompts, and have experimented with agents, skills, or custom workflows. You know that the quality of AI output depends on the quality of your input.Process-minded, not just code-focused — you care about how we work, not just what we build. You're excited to establish and refine workflows, tooling, and team practices as we figure things out together.Enthusiastic about improvement — you constantly ask "how can we do this better?" and bring new ideas to the table.Comfortable with ambiguity — this is a new project, and things are still taking shape. You thrive in environments where not everything is defined yet and you can help create structure from chaos.Comfortable working from specifications rather than existing code — you can read a specification and ask the right clarifying questionsFamiliarity with modern development practices : clean code, design patterns, testable architectureNICE TO HAVE
